Water in fuel question

Water in fuel question
On my last trip i was getting water in fuel lights. Stopped and drained the separator. I got about a 1/4 teaspoon of water and what looked like rust scale. Got the light again and had a mechanic drain it. He did into an oil drain pan so I have no idea what came. out. Got it again and I drained it. very little water but still to rust scale. I gave it an extra shot of Stanadyne and continued. The light came on again but went out shortly thereafter.
My question is what was that rust scale like matter I saw in the fuel. I did not touch it so I can not say for sure it it was in fact rust or algye.
I am home now and will drain the separator but could use some ideas as to what to look for.
The truck does sit for weeks at a time.

The rust builds up in the separator over time from a small amount of water being in there. Then when you get a tank with a good amount of water in it which it seems you did the first drain you will see that "rust water". The second drain might have a hint of rust at the very beginning but should be mostly clear.
The newer separators are small and will need frequent draining with a bad tank of fuel. Many times it is best to drain off the tank and put fresh fuel in. You may be able to put the bad fuel in a container and let the water settle.

That is what I had as well. I got the WIF lite several times a week and then I cleaned it.. haven't had the WIF lite in a couple of years now.
I pulled the driver's side front and rear tires up on ramps (I have heavy-duty SUV ramps - don't use the cheap ones for automobiles !) so the Ex was leaning - to help the HFCM (Horizontal Fuel Conditioning Module - where the filter and WIF drain is) drain better.
I pulled the drain (you DO have the upgraded knurled **** one right!)
I then used carb cleaner (some say use Brake Cleaner instead) with the straw and gave the inside a real thorough cleaning into a pan. I pointed that straw all around inside and got a large amount of algae (rust/brown colored).
Put the drain plug back in and voila - no issues since.

I had the same issue as Misky and followed the same procedure to get rid of that annoying WIF light.
I however did not have the knurled **** upgrade, and had a stripped original plug.
Here is how I removed it.

The little bit of water helps algae grow (it's a rust color..).

To prevent fuel drain from the tank while working is there a place where I can just pinch off the line?
I guess I brought this issue on myself. I had gotten lax in putting Stanadyne Blue in with each fueling.
Will post on filter condition when I do the work.
